DAVID C. BOYD, 0F GALION, OHIO, ASSIGNOR TO THE GALION IRON WORKS ANDMANUFACTURING COMPANY, OF GALION, OHIO, A CORPORATION OF OHIO.

CULVERT.

To all whom it may concern:

Be it known that 1, DAVID C. Born, a citizen of the United States,residing at Galion, in the county of Crawford and State of Ohio, haveinvented certain new and useful Improvements in Culverts, (Case 13,) ofwhich the following is a specification.

This invention has for its primary object a simple, durable andefficient construction of culvert designed particularly for use as acrossing culvert or pipe, or wherever the conditions are such that arelatively shallow culvert is desirable.

A further object of the invention is an improved cast iron culvert, thetwo longitudinally extending parts or sections of which that are laidone upon the other to form the complete pipe, being provided withattaching ears or lugs formed with holes for the reception of bolts orsimilar fastening devices, if desired, the ears on one side of theculvert and on one section thereof being formed with vertically disposedpositioning pins designed to be accommodated in the adjoining ears andthe ears on the opposite side of the culvert and on the other sectionbeing correspondingly formed with pins adapted to be positioned withinopenings formed in the adjoining ears of the first named section,whereby the bolts or similar fastening devices may be omitted, while atthe same time, the parts will be held together as against relativelongitudinal displacement and a certain degree of contrac tion andexpansion provided for, while at the same time, when the device isinstalled as a crossing culvert, with one section at the surface of theground and exposed, said section may be easily lifted and removed andreplaced, as for example, when it is desired to flush or otherwise cleanthe culvert out.

With these and other objects in view, as will more fully appear as thedescription proceeds, the invention consists in certain constructionsand arrangements of the parts that I shall hereinafter fully describeand claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which- Figure 1 is aplan View of a culvert constructed in accordance with the present invention, parts being shown broken away, and Fig. 2 is a side elevationwith one sec- Specification of Letters Patent.

tion slightly raised from and in juxtaposition to the other.

Corresponding and like parts are referred to in the followingdescription and designated in the accompanying drawing by like referencecharacters.

Referring to the drawing, the numerals 1 and 2 designate, respectively,the sections of my improved culvert, the section 1 in the presentinstance being somewhat cylindrical, as shown, and disposed lowermostand the other section being flat throughout almost its entire surface,with side flanges 3 which preferably terminate in strengthening heads 4adapted to contact with and lie upon corresponding heads 5 formed on thesection 1 at the side edges thereof. Each of the sections of the culvertis formed on each of its side edges with a pair of longitudinally spacedand longitudinally elongated lugs or ears (3, the ears of one sectionregistering with the ears of the other, as clearly illustrated inFig. 1. WVhile in the present embodiment of the invention there is apair of cars formed on each side of each section, it is to be understoodthat the invention is not limited to this number of ears, but that othernumbers may be employed. Each ear 6 is formed with a bolt hole 7, thebolt holes of the overlying ears registering with each other for thereception of the bolts 8 if it is desired to use the same. Furthermore,the ears on one side of the section 1 are formed with verticallydisposed upwardly projecting pins 9 receivable in apertures 10 formed inthe adjacent ears of the other section, and on the other side of theculvert, the section 2 is correspondingly formed on its ears 6 withvertically disposed downwardly projectiug pins 9 adapted to be receivedin corresponding apertures 10 formed in the other ears of the firstnamed section. It will thus be seen that even though the bolts beomitted, which is a desirable thing to do under some conditions, as forexample, where the culvert is used as a crossing culvert at the surfaceof the ground and it is desired to open the culvert from time to time,the pins 9 in the apertures 10 will permit of the ready removal of onesection from the other, whereas when the parts are in position one uponthe other, all liability of accidental displacement is preeluded.

In the present embodiment of the invention, the culvert is formed at oneend with a bell 11 to receive the end of another culvert or pipe, but itis to be understood that this bell need not extend entirely around theend of the culvert, but be partially or entirely omitted so far as theformation of the upper or cover section 2 is concerned. And it is; alsoto be understood that under some conditions, the parts may be reversedfrom that illustrated in the accompanying drawing and the section 1 bedisposed uppermost and the section 2 lowermost, as for example, when arelatively shallow culvert is desired with a substantially flat bottomand disposed underneath the surface of the ground.

WVhile theaccompanying drawing illustrates what I believe to be thepreferred embodiment of my invention, it is to be understood that theinvention is not limited thereto, but that various changes may be madein i the construction, arrangement and proportlons of the parts withoutdeparting from the scope of the invention, as defined in the appendedclaims.

What I claim is 1. A culvert comprising sections adapted to rest oneupon the other to form a horizontally and longitudinally divided pipe,both sections being formed at their sides with overlapping ears, theears of one section being formed with pins and the ears of the othersection being formed with apertures in which said pins are looselymounted, whereby one section may be raised directly from the otherwithout the necessity of removing any fastening devices.

2. A culvert comprising sections adapted to rest one upon the other toform a horizontally and longitudinally divided pipe, both sections beingformed on their side edges with laterally disposed longitudinally spacedand longitudinally elongated ears, the ears of one section registeringwith and overlapping the ears of the other section, the ears on one sideof one section being formed with vertically disposed pins and theadjoining ears being formed with openings in which said pins are looselymounted and the other section being formed on the opposite side of thepipe in its ears with vertically disposed pins, while the adjoining-earsare formed with openings in which said last named pins are looselymounted.

8. A culvert comprising sections adapted to rest one upon the other toform a horizontally and longitudinally divided pipe, both sections beingformed on their side edges with laterally disposed longitudinally spacedand longitudinally elongated ears, the ears of one section registeringwith and overlapping the ears of the other section, the ears on one sideof one section being formed with vertically disposed pins and theadjoining ears being formed with openings in which said pins are looselymounted and the other section being formed on the opposite side of thepipe in its ears with vertically disposed pins,'while the adjoining earsare formed with openings in which said last named pins are looselymounted, all of the ears being formed with bolt holes, said bolt holesof adjoining ears registering with each other, for the purposespecified.

In testimony whereof I aflix my signature 7 in presence of twowitnesses,

DAVID C. BOYD.
